When Spike and the CMC get in a bind, his true nature is revealed to Ponyville and all of Equestria.

Spoiler Alert: Spike is often overlooked. This isn't one of those times!

NOTE: This story is not going to be canon-compatible for very long. But Spike fans like me would most likely wish it would be.
